8.1 vs Duramax engine replacement

It is studded and deleted, he's a diesel mechanic. And his truck went a 12.8 in the quarter mile. (It's a single cab 2wd) so its light, that's why. I respect what you have to say, I just don't see anyone getting 1000 ft pounds out of a bone stock lb7

Watch the dyno pulls on the duraburb youtube channel.  Not an LB7, but various, later, Duramax engines.

Yeah the later duramax models, 1000ft pounds is easily achievable. The LMLs make around 850 from the factory, and the L5P makes over 900, but cannot be tuned
